Puneet Dixit 35d235542e fix: validate devEngines runtime onFail (#11822)
Fixes #11818

## Summary

`devEngines.runtime` / `engines.runtime` entries with `onFail: error` or `warn` silently did nothing — only `onFail: download` had any effect. This PR wires up validation for all three supported runtimes (node, deno, bun).

- Add `getSystemDenoVersion` / `getSystemBunVersion` and a generic `getSystemRuntimeVersion(name)` dispatcher in the runtime-version helper package.
- Walk each runtime entry in the manifest during pnpm startup, compare to the live system runtime, and throw `ERR_PNPM_BAD_RUNTIME_VERSION` (or warn) on a mismatch. Invalid ranges (e.g. `"invalid range"`) are reported instead of crashing `semver.minVersion`. Missing runtimes ("no Node.js on the system") get the same error path.
- The shell-out for deno/bun only runs when the manifest configures them AND `onFail` is `error`/`warn`. `download`/`ignore` short-circuit, and projects with no runtime pin pay nothing. Memoized per runtime.
- `pnpm --version`, `pnpm --help`, and `pnpm <cmd> --global` are exempt from the check.
- Rename `@pnpm/engine.runtime.system-node-version` → `@pnpm/engine.runtime.system-version` to match its broader scope; hoist `RuntimeName` / `RUNTIME_NAMES` / `isRuntimeAlias` to `@pnpm/types` so callers don't need to depend on `pkg-manifest.utils` just for the alias check.

## Tests

- `pnpm --filter pnpm run compile`
- `pnpm --filter pnpm exec jest packageManagerCheck.test` — 42 passing. New coverage: node/deno/bun version mismatch, invalid range, missing range, multi-entry runtime arrays, `engines.runtime` path (not just `devEngines.runtime`), and the `pnpm --version` exemption.
- `pnpm --filter @pnpm/engine.runtime.system-version test` — 10 passing, 100% statement coverage; unit tests for each helper and the dispatcher.
- Manual end-to-end smoke tests against the rebuilt bundle for deno and bun version mismatch.

## Release Notes

* **New Features**
  * Added runtime version validation for Node.js, Deno, and Bun. The system now enforces `devEngines.runtime` and `engines.runtime` declarations with configurable failure behavior (`error`, `warn`, or `ignore`).
  * Enhanced error messages for runtime version mismatches with helpful suggestions for overrides.

* **Improvements**
  * Improved system runtime detection and version checking across multiple runtime environments.

minor minor patch patch

Validate devEngines.runtime and engines.runtime version ranges for node, deno, and bun when onFail is set to error or warn. Previously these settings only had an effect with onFail: 'download' — the error and warn modes silently did nothing #11818. Violations now throw ERR_PNPM_BAD_RUNTIME_VERSION.
